Ronco Plastics 52H - 33 Gallon End Dump RV Holding Tank (No Rails) (46.0" x 16.0" x 12.75")

Sixteen inches wide, twelve and three-quarters deep: the 52H is the narrow-and-deep answer in Ronco's 33 gallon class, a 46 x 16 x 12.75 inch molding for the slot between a frame rail and a holding bay wall where wider tanks never had a chance. Depth is the compensating dimension, and it buys good drain-down geometry toward a bottom outlet along the narrow floor.

The blank weighs about 25 pounds and serves gray or black water exclusively; H-series tanks carry no potable rating. Full, plan for roughly 275 pounds, 33 gallons at 8.34 pounds per gallon, on a footprint that concentrates load in a narrow strip, so the supporting structure below should run the tank's full length.

The rest of the 33 gallon family covers other geometries: the 15H leads the undimensioned shapes, the 38H sits one gallon down, and the 20H side-dump goes long and shallow at 63 x 20.25 x 8.5. Browse RV holding tanks for the full set. One Source Plastics is an authorized Ronco Plastics dealer.
